This visualization presents the ten most populous countries as horizontal bars, with country names on the vertical axis and population counts on the horizontal axis, formatted in billions. It uses React to render SVG elements, with D3’s `scaleBand` and `scaleLinear` to map data to coordinates, and `csv` to load the UN World Population Prospects 2019 dataset. The chart’s styling includes Poppins typography and a teal color scheme, with axis labels and a tooltip showing the population value via a `<title>` element.
